Default EFIlive automatic fueling adjustment?

I read on the EFILive site that it is able to automatically adjust fueling after scanning. Does anyone have any experience with it and does it really work? I would imagine that having that feature would take a lot of the work out of tuning closed loop.

Yes, it's called Auto VE. Using a wideband lets you autocalibrate the VE table (other manufacturers have this as well)

Yes, before any other manufacturers had it.

AutoVE works great. The main benifit that EFILive offers is you can remove your transitions on TPA to give a better and more accurate results. This is done by a filter (more then one can be applied) and provides a constant and consistent tuning. I do not believe HPT offeres the ability to filter out large transitions in throttle which in turn can throw off the fueling. If you are interested in EFILive, feel free to PM or email me with any questions and I will be happy to help you out. I am offering specials this month on EFILive and Innovate widebands.

Of course we do.
Per the help files:


Histogram Filters

If you define a filter, the filter must return a value of 1 (true) to add the current cell to the histograms data. If the filter returns 0 (false), the frame will not be added to the histograms history.

You can combine filters using AND and OR statements.

Examples of valid filters are:
[SENS.90] > 50
[PID.11.MET] < 85
[PID.11.MET] < 85 AND [SENS.90] > 50
[PID.11.MET] < 85 & [SENS.90] > 50


Enhanced IO Output Triggers

Enhanced IO Outputs Triggers are defined just the same as the Histogram Filters.

Supported Binary Operations

+ Sum up two operands.
- Subtract two operands.
* Multiple two operands.
/ Divide two operands.
^ Raise to a power.

Supported Relational Operations

> If x > y result is 1 otherwise 0.
< If x < y result is 1 otherwise 0.
= If x = y result is 1 otherwise 0.

Supported Conditional Operations

AND If x = 1 and y = 1 result is 1 otherwise 0.
OR If x = 1 or y = 1 result is 1 otherwise 0.
& If x = 1 and y = 1 result is 1 otherwise 0.
| If x = 1 or y = 1 result is 1 otherwise 0.

Supported Functions

sin(x) Returns the sine of x where x is in radians.
cos(x) Returns the cosine of x where x is in radians.
tan(x) Returns the tangent of x where x is in radians.
abs(x) Returns the absolute value of x.
round(x) Returns the whole number nearest x.

Ken, so in that explaination, can they state that they don't want to use data where the tpa has changed less then 5% per 100ms? I don't honestly know.

LOL, that was the most confusing thing i've seen hahahaha. EFILive's filter setting are extremely simple with drop down menu's of what settings you want and how they are applied, much simpler then a combo of multivariable calculus, throwing in some vector functions and a little C++ all hand typed out in notepad.... lol.

Best Regards,
Adrian

WTF, the guy asks about EFI and it turns into a Pimp my software thread (Super Sport X2) Frick for what these software packages cost I can't believe you guys couldn't afford to let one get away once and awhile
